I included a simple batch file installer for Windows 9x/ME/XP (not 2K, though I've tought about making a seperate installer or an "if/then" - just never got around to it). Run the batch then open the C:\Windows\Fonts folder and let Windows parse / cache everything.

On a Mac, you may still be able to use the fonts, if not the installer. I just don't know what types of fonts Macs natively support.
